+## AOB
+
+(5 min. max; tech. Discussion should be highlighted to relevant people and rescheduled)
+
+## Main Topic
+
+Technical discussion focusing on [Java version 17 suupport in OMERO.server](https://github.com/ome/openmicroscopy/issues/6383)
+ - Feedback on process welcome
+ - Java programming language - LTS releases
+ - Core OME repos in Java. Require Java 8+, Some Java 11
+ - Users need JRE to run apps
+ - Devs need JDK - OpenJDK released 2007 by Sun Microsystems
+ - Now multiple JDK distributions
+ - JDK builds only get support for 6 months
+ - Other vendors ship their own OpenJKD releases with different EOL
+     - e.g. RedHat JDK 11 EOL Oct 2024
+ - Bio-Formats 6.12.0 added support for Java 17
+     - recently added support for Java 21
+ - OMERO server doesn't yet support Java 17 - reflection issue
+     - Strongly encapsulated - can't access protected/private Java API methods
+     - workaround: use --add-opens to JVM
+     - also need --add-exports to avoid IllegalAccessError
+     - This allows us to run OMERO.server on Java 17
+     - These options not supported for Java 8.
+ - Next steps:
+     - review dependencies etc to remove need for reflection
